Unleash Precision with SHILEN’s 6.5MM Caliber Barrels
All the loving care of the best stock maker and the meticulous attention to detail of the master machinist will not make a gun shoot any straighter than the accuracy capability of the barrel used. It is the insides of a barrel, that very small and vital area of lands and grooves over which the gunsmith has no control, that can determine whether the finished work of art is for shooting - or “just for looks”.
Craftsmanship Over Cost
Craftsmanship, not price, determines the quality of a barrel. A customer willing to invest in a custom gun should not economize by ordering “just any old barrel so long as it’s cheap”. Such a request jeopardizes your reputation as a gun builder. As your supplier, we are laying our reputation (and yours, too!) on the line by offering you barrel blanks. They must be of the highest quality, or we face significant trouble!
Quality Assurance
We believe that the BrownellS Barrel, made for us by Ed Shilen, will enhance your stature within your trade. Shilen barrels, whether chrome moly or stainless, are rifled with six lands and grooves using the “Cold Forming” process with carbide dies manufactured in Shilen’s own plant under the most rigid controls. This rifling method achieves extremely close inside uniformity from breech to muzzle.
Inspection and Standards
- Finished barrels are air-gauge inspected (air-gauged sensitivity is .00005" - five-one-hundred-thousandths!)
- 6X borescope inspected.
- All barrels, .22 through .30 caliber have groove tolerances within .0005" and uniformity within .0003".
- No straightening is done, and all barrels are completely stress-relieved.
- All stainless steel barrels are hand lapped at the factory.
Only those barrels passing all spec tests are offered to the trade. Any barrel even slightly “suspect” is restarted through the production process and bored to a larger caliber. This meticulous approach ensures that quality and reputation are maintained, making the barrels slightly more expensive to produce but vastly greater in quality and ultimate performance.
